This one’s a no-brainer. Music is a key part of mobile, and Andy Rubin doesn’t want to cede that to outsiders like Spotify and Pandora. (Android’s effort to break into music via a download store and a scan-and-match locker have had little take-up.) And this one is relatively easy for music owners to sign off on, since they’ve already bought into the Spotify model — free ad-supported music that pushes users into a $10-a-month mobile offer.

As previously reported, Google’s YouTube unit wants to do … something with a subscription service.
At a minimum, YouTube is trying to collect the rights to sell music, in both audio and video form, via subscriptions. But it hasn’t told music owners what it actually wants to do with those rights, and it hasn’t shown outsiders a prototype of what it’s working on.
